My boyfriend and I had sex for the first time last night. Well, his penis didn't go all the way in because it hurt, and I asked him to stop. So it was in me for about 15 seconds. He didn't ejaculate, but he wasn't wearing a condom. I know it was stupid. but now I'm worried about pregnancy compiled with the fact that wasn't ready.

If your period is more than two weeks late, we suggest that you take a pregnancy test. Additionally, you may want to consider getting a panel of STI tests done as well.

As far as your regret, well, try to go easy on yourself, and let this be a lesson for all your future behaviors - sex-when YOU want to and are ready; protected sex ALWAYS unless you are trying to have a child.
